t the present `time automobiles are constructed 'without` 'any consideration being given to'.the@point` or place oi attachment ofthe bumpers.` `\'l"ui-ihas made' it necessary" for the !bum'perf manufacturers to design different# types of bumpers for iiiti'erent types of c'ars. Attemptsgbave been' matie to meet thissituation Iby providing adjust mente in the bumper supporting arms of various `forms and descriptions in order to adapt the bumpers to ya number of types of automobiles. Although the aim has been to secure a universal type oi' bumper, expert ence has shown that. 'this is impoesible through adjustable features in the bumper. Each year the automobile manufacturers make` changes which require the yiuunper manufacturers to make the changes in one or more of their bumper supporting arms. This absence of cooperation between the manufacturers ot automobiles and the manl 'in section, or

ufecturers of the bumpers has added inatcf rially to the cost of the blilmpers and to the sellinga price thereof.

According to `this invention, provision i has been made" whereby, notwithstandinna the yearly changes in 'the/automobile itseli the points of the attachment of the bumpers will not Vary.

lin` the embodiment of the invention shown in Figs. l, 2, and` tl, It ii'uiicetes 'the bumper bar which supported near opposite ends by two supporting arms, lach` of these supporigin@` arms, in this inst-ance, emboies an outer member 2 anni an inner member 3, theV outer member being guided in the inner member, and a coiled. springerY being; interposefl between the two men'lbers topermit the yielding of the bumper bar l on impact to absorb the-shock ci. euch impact. While in its embodiment the resilient or yielding portion of the bumper is provided in the bumper supporting arms, it is apparent that the invention is not iimi'ted to this arrangement, but that the yieldingf or resilient por tion may be provided in any portion of the bumper in advance of the connection of the bumper supporting arms with vthe vehicle frame.

The connectionbetween each bumper-supporting arm and the vehicle frame embodies a portion 5 on each arm, said portion preferably being in the form of a tapered inner end which is detachably yet rigidly litted within a tapered socket 6 which, in the embodiment shown in Figs. 1,2 and 3, is formed integrally withv the bracket 7 on the inner side of the latter, this bracket being in the form of a casting having an inner portion riveted at 8 in the end of the channeled frame bar 9 of the Vehicle and en outer portion projecting for the purpose ot' attaching with the usual vehicle spring. The tapered end 5 may be held in the tapered socket by a bolt passed through a y sher 21 abutting the inner end of the socket.

From the foregoing it will be seen that a bracket construction is provided, which y is permanently attached to the frame of the vehicle.A Two' sockets` are 4provided whose axes are parallel and preferably horizontally arranged, those in some embodiments being above the projecting ends of the brackets to which the usual vehicle springs are secured. i

The invention is also not limited to the use of these brackets on front bumpers alone,` but the brackets may be positioned at the rear of the vehicle for the attachment of rear bumpers: The bumper supporting arms may thus have a standard termination at their inner ends to detachably yet rigidly connect with the socketed brackets. By this means all clips which are liable to work loose may be eliminated, and also all justments to permit the horizontal positioning of the bumper arms may lbe dispensed with, thus reducing the cost of manufacture of the bumper. The socketed brackets will be arranged in a-definite posi` tion with reference to the treads oi' the forward wheels by the designers of the different automobiles, and the manufacturers of the bumpers can then construct the supporting arms of a standard length so that the bumper bars will lie at the proper position with reference to the treads of thenwheels.

Vbeyond the channel barsockets being parallelua bumper bar and two l ner member rigidly and detachably secured in one of the sockets, an outer member guided on the inner member and connected tothe bumper bar, and springsinterposed between the inner andthe outer members ofthe bumper supporting arms.

2. In combination with a bumper bar, and two supporting arms therefor, two brackets permanently secured to the vehicle frame and each provided with a socket in which the inner end of a bumper supporting` arm is rigidly and detachably secured, the bumper being provided with a resilient portion permitting a yielding action beyond those portions of the bumper whichI directly connect with the socketed brackets.

3. In combination with a channeled frame bar of a vehicle, a bracket secured to one endo the bar and having a socket formed therein, and a bumper supporting arm rig'- idly and detachably secured in the socket.

4. In combination with a channeled frame bumper supporting arms each having an in- I bar of a vehicle, a bracket secured to one' end of the bar to project therefrom and having a socket formed therein to one side of the frame bar, and a bumper supporting arm rigidly and detachably secured in the socket.

5. In combination with a pair of frame bars of a vehicle, brackets each permancntl secured to one of the frame bars andcaci havingva tapered socket, the larger end of which is disposed outwardly with Areference to its frame bar and the two sockets having their longitudinal axes parallel and horizontally arranged. f f
